Summary: Also another owner here for whom the ATH-A900 is the first pair of good headphones.
They definitely stand out with their styling and massive aluminium cups. I just dig circumaural headphones. They're just so much more comfortable that on-ears.
Summary: Sound is only a little better than average at best.
Treble: Analytical sounding and a little bright for my tastes, a little fatiguing, liquid though lacking absolute detail, some air, compressed sound stage.
Pros: Neato blue color, great build quality, comfort, decent sound for closed phones.
